To all w/wntitnuty' concer-n: i

Be it known that-L'Gnonen B. GARLINGHoUs-n,

of North vI llaclison, inthe county of Jefferson and State of Indiana, have invented a new and useful 1insame, lreference being had to the accompanying draw- Figure 1 being a plan ofthe same;

Another important'feature consists in providing the lifter, which' serves as aV guard to protect thefmaiu frame frlnan accumulation 'of `dirt, and, by over-A riding the ridgeof earth left bythe scraper-board, keeps the v,c or'nerofthe frame from' cuttingV in too deeply, and assists in the` work of levelngand grading.

Another important feature consists in the reversi-- bility ofthe 'dili'erent parts.so that the scraper may work right 'or left-handed at plea-sine.`

the length ofthe board.

xaxle, a, which rotates :horizontally on a verticalv bolt, b.

0n thelower yendfof this bolt is a horizontal wheel, c, working in amortise through the side frame of the scraper, andot' sndicient diameter to bear against the' insideof -the-push-'wheel GL As the axle of thislatterwlieel turns `horizontally."on the same vertioal'bolt as thefwheelyc, it will be seen that, at whatever angle -i the push-Wheel is set, its innersnrface will always remain'y incontact with the periphery of the wheel c,

which serves to sustain the push-wheeland prevent too great a ,strain being thrown on the axle ofV the latter. To enable the operator-to set thev push-wheel at any desired angle, the end of the axle a is provided with a strip pierced with holes for -the reception of a pin; by

this arrangement, as-clearly shown in g. 1, this end may be accomplished, and the wheel held-firmly in then desired position.

The scraper-board B has a slight lateral curvature, is providedwitha metallic strip, e, at its lower edge, and is rounded at the ends. i

It has also-a series of mortises, ff, with bars across themsaid bars being secured to the back of the scraper-board, as seen in ng. 3; these are for the purpose of attaching the draft-chain F at any desired point in In iig. 3 ,are also shown theeye-bolts hlt, byuvwhich theboardl is secured to the frame A; and also the ringe', to which is attached a lever, j..

e This lever operates ,'througl1 the medium of a hook, k, and ratchet, l, to regulate the angie ofthe scraperboardd with the ground to hold it rmly in its place,

and permit it, when the lever isfreeld from the ratchet, .to dump itself.

' In lig. 2 is shown the peculiar form of hook used to .connect the scraper-board with the frontend of the i framel A, m representing the hook, n the slot-iu the end `ofthe frame, and o the pin for securin'gthe hook in place, it being first engaged with one of the eye- -holts h inthe scraper'. (See iig. 3.)

The rear end of the scraper is secured, by means or' theother eye-bolt h, to a bar, E, through the medium of ahook, p, attached to vsaid bar, as seen in fig. 7'.

This bar extends, through mortises in the lside 'fi-ames; diagonally across the frame, asindicated by .dotted lines in iig. 1, and is secured byl a pin, fr.

'lhe incline-board I) is simply a; smooth hoard secured to the main frame Vby battens and screws, substantially in the manner indicated-in s. 1 and 4.

Whenit is desired that the scraper belsetin Vthe ncl um,

position shown in fig. 5, the bar E is inserted in two other mortises through the side f aine, forward of those last mentioned, and also indicated by dotted lincs in fig. 5. In this position of the scraper-board it is considered preferable to att-ach the draft-chain F in the central mortise. A change is also necessary in the position of the ratchet l, and longer hook 7.1 will have to be provided. i

As all the bolt-holes, pin-holes, and mortises are du plieated, and the main frame precisely alike on both sides, it will be unnecessary to describe in detail every operation necessary to reverse the scraper, so as to scrape'on the left instead of the right, the latter arrangement being the one shown in the drawing; but I will state that, in this event, the push-wheel device and the incline-board I) exchange places, and the scrapeiboard B changes ends, the bar E taking the place of the hook m, and 'rice versc. Sonie minor changes will also be necessary, but these are too ohviousto need description.

It may be necessary to state that, in its operation, the scraper works, usnall y, longitudinally with the axis of the roadway to be thrown up, the scraper-board heing on the inside both in `going and retin-nino'.

y As the scraper-board is usually set at one ot' the angles shown in igs. 1 and 5, the breadth ot' the ground graded at once passing over is regulated and governed by the angle atwhieh the-push-whcel is set, or, in other words, the angle it makes with the line of draft. lhis also ,governs the amount of draft or power required; for, if the push-wheel is inclined inward considerably, its constant tendency is to push the rear end ofthe scraper inward, thus, by forcing the scraperboard into a position approaching a right angle with the roadway, greatly increasing the breadth graded. 1f the push-wheel is set to coincide with the line of draft, the amount of draft and the breadth of ground graded will be a minimum.

A fender or guard for the push-wheel is shown,`but, as it is not new and very simple, no description-of it has been given,

I do not claim the triangular for it is old; but

What I do claim is- 1. lhc device, consisting` ofthe push-wheel C, horizontal wheel e, axle u, and bolt b, or its equivalent, arranged to operate substantially in the manner shown, and for the purposes set forth. s

2. ln a road-scraper, the incline-board D, when conform of the scraper,

I structedand attached as shown, nml-arranged to operate substantially in the manner and for the purposes set forth.

3. A road-scraper, soA constructed that the scraperhoard 13 may be reversible and the push-wheel C and the ineline-board 1) interchangeable, andthe whole lnaehine be thus made `to operate either right or lefthanded, when the said parts are constructed and arranged to operate in the manner shown, and for the Vpurpose set forth.
